Say that the Utopian reasoners are
visionaries, unfounded; that the state of virtue and knowledge they
suppose, in which reason shall have become all-in-all, can never take
place, that it is           with the nature of man and with all
experience, well and good--but to say that society will have attained
this high and "palmy state," that reason will have become the master-
key to all our motives, and that when arrived at its greatest power it
will cease to act at all, but will fall down dead, inert, and senseless
before the principle of population, is an opinion which one would
think few people would choose to advance or assent to, without strong
inducements for maintaining or believing it.
